LZ Interop Validation (V, C, Python)

This tool validates:

• V compress/decompress roundtrips for all formats: lz77, lz78, lzw, lz4, lzss, lzma, lzjb
• a C lz77-like reference implementation
• a Python lz77-like reference implementation

The C/Python references are intentionally simple so the benchmark is easy to run without external dependencies.

Run

cd /home/jalon/git/v
./vnew run vlib/compress/lz/interop/lz_interop.v 2>&1

Optional args:

1. validation rounds (default: 40)
2. input size in bytes (default: 524288)

Example:

cd /home/jalon/git/v
./vnew run vlib/compress/lz/interop/lz_interop.v 25 262144 2>&1

Output

The tool prints validation status lines only (no timing output).

When helpers are available, it also cross-validates compression/expansion interoperability with V (lz77) in both directions:

• V compress -> C decompress
• C compress -> V decompress
• V compress -> Python decompress
• Python compress -> V decompress

If cc/gcc or python3 are missing, that row is skipped with a message.
